| 摘 要： | 采用时间演化算符和数值计算方法,研究了两全同二能级纠缠原子与热态光场相互作用过程中光场的量子特性,结果表明:两原子初始纠缠度和光场初始强度对光场的量子特性均有影响.对于适当的初始热光场强度,光场显现出了非经典特性.这种非经典特性随着初始热光场强度的增加而增强,但这种非经典特性并不总是随着原子初始纠缠度的增大而增强,而是呈现出一种复杂的关系.

| Abstract: | The quantum properties of the light field in the system of thermal radiation field interacting with two identical entangled atoms are studied by means of time evolution operator and numerical calculations.The results show that the entanglement degree of the initial two identical two-level entangled atoms and the intensity of the thermal radiation field have influence on the quantum properties of light field.For the initial light field with appropriate intensity,the non-classical properties of the light field will appear.The non-classical properties are increased by the growth of the intensity of the initial thermal radiation field,but the influence of the entanglement degree on the non-classical properties is complex. |
